SUBSOILER.

Specification of Letters Patent.

Patented May 5, 1914.

Application filed August 6, 1912. 1 Serial No. 713,665.

To all whom it may concern Be it known that I, WILLIAM A. DOLEZAL, acitizen of the United States, residing at Burke, in the county ofGregory and State of South Dakota, have invented new and usefulImprovements in Subsoilers, of which the following is a specification.

This invention relates to the class of farming implements and pertainsespecially to the class of subsoilers adapted to be attached to anordinary sulky-plow.

An object of my invention is to provide a subsoiler the point of whichcan be raised and lowered from the operators plow seat.

Another object of my invention is to provide a spring for holding thesubsoiler in the ground and at the same time allows it to be raised upshould the point come in contact with a stone of other hard substancewithin the ground.

A further object of the invention is to provide a lever connected to arod which in turn is secured to an iron strip for raising and loweringthe subsoiler by operating the lever.

With the foregoing and other objects in view, my invention consists insuch details of construction and arrangement of parts as will behereinafter more fully described and pointed out in the appended claims.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which,

Figure 1 is a side elevation of the subsoiler attached to a sulky-plow,the dotted lines showing the raised position thereof, and Fig. 2 is atop view.

In the drawings the numeral 1 designates the subsoiler beam, to which issecured by any suitable means the subsoiler point 2. This beam 1 is heldaway from the sulkyplow beam 3 by means of a bushing 4: secured at oneend to thesaid beam 3 and at the other end to a clevis 5 which is boltedor otherwise fastened to the beam 1 to form a pivot connection betweenthe subsoiler and the sulky-plow.

Pivoted by means of a fork 6 to the rear end of the beam 1 is a rod 7,which extends upwardly at an angle and terminates in a head 8. Near thefront end of the said beam and likewise pivoted thereto by means of afork 9 is an iron strip 10 also extending upwardly at an angle so as tomeet the said rod'7. The upper end of this'strip 10 is enlarged at 11and has a hole therein to permit its sliding up and down on they meansof connection between the said lever 15, and the strip 10.

The clevis 5 is provided with a brace 18 so that the subsoiler may beadjusted to the beam 3 at any desired height and held securely theretoby means of braces 18.

It will be seen that when it is desired that the subsoiler should beraised, all the operator has to do is to push the hand-lever 15 forwardthereby pulling the connecting rod 16 which in turn lifts the strip 10until it strikes the knob 8 thus causing the rear end of the beam 1 andthe point 2 to be lifted entirely free of the ground as shown by thedotted lines Fig. 1.

I desire it to be understood that I may make slight changes in thecombination and arrangement of parts without departing from the spiritof the invention provided such changes come within the scope of thesubjoined claims.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is 1. In combination with a sulky plow, asubsoiler attachment therefor including a beam, a clevis rigidly securedto the forward end of the said beam, means for pivotally and adjustablyconnecting the beam of the sulky plow to said first mentioned beam, arod pivotally connected to the rear end of the said first mentioned beamand extending upwardly at an acute angle thereto, a strip pivoted to theother end of the said beam having an opening formed in the free endthereof through which the said rod extends, a coil spring disposed toembrace the said rod for yieldably supporting the said strip thereupon,and means connecting the said strip to the said plow for raising andlowering the subsoiler, as and for the purse set forth- 2. Incombination with a sulky plow, a subsoiler attachment thereforlncludlng; a beam having a clevis fixedly secured to the forward endthereof, a bushing adjustably v said strip having an opening formed inthe free end thereof through which the said rod extends, a springarranged to embrace the said rod for yieldablv supporting the stripthereupon, a hand lever pi'vot'ally secured to the said plow, and a rodconnecting the said lever to the saidstrip for raisin; and lowering thes'ubsoiler according to the operation of the said handle, as and for thepurpose set forth.

3. In a subsoiler, the combination, of a sulky-plow, a pivot connectionbetween the subsoiler and the plow, a bushing for holding the two apart,a rod pivoted to the rear end of the subsoiler beam and extend ingupwardly toward the front thereof, a

strip pivoted to the other end of said beam and slidable on the saidrod, a coil-spring mounted on the'said rod, a segmental rack carriedtheplow, a hand lever operated inconnection therewith, and a rodconnection between the lever and the strip sothat the working of .S aidlever will raise and lower the subs oiler.
